Inventor: MAEDA IKUO
IPC: G11B7/135
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To make a whole optical pickup small in size and light in weight by making an optical system and a detecting system small in size and light in weight even when a beam forming means is provided. SOLUTION: In this optical pickup, a deflection mirror 4 is arranged between a beam splitter 3 and an objective lens 5, when a laser beam from a semiconductor laser travels to a recording medium 6 through a coupling lens, the beam splitter 3 and the objective lens 5, the mirror 4 has the function of an optical path changing means for changing the direction of the laser beam traveling from the beam splitter 3 to the objective lens 5 and the function of a beam forming means changing the diameter of the laser beam at this time in one direction, expanding/forming the shape of the laser beam and making the beam travel toward the objective lens 5.

Title: Thermal head
Inventor: MURANAKA MASAICHI
IPC: B41J2/335
Filed: 1989-03-22
Abstract: PURPOSE:To make not only an ink sheet hard to generate wrinkles but also heat easy to dissipate toward recording paper at the time of recording by forming the surface in contact with a platen roller in opposed relationship into the curved recessed surface almost corresponding to the periphery surface of said roller and providing a heating element to the part of the curved recessed surface. CONSTITUTION:The surface of the thermal head 14 in contact with a platen roller 1 under pressure through an ink sheet 2 and recording paper 3 is formed into the curved recessed surface almost corresponding to the lateral surface of the platen roller 1 and heating elements 15 are provided to the curved recessed surface in an array state so as to be parallel to the axial direction of the platen roller 1. As a result, since the platen roller 1 and the thermal head 14 become surface contact but not line contact, the heat generated from the heating elements 15 becomes easy to dissipate toward recording paper 3 and the damage of the thermal head accompanied by the overheating thereof can be prevented. Further, by eliminating the too much variation of the magnitude of pressure contact force at the recording part where the heating elements 15 are positioned and at the parts before and behind said recording part because of surface contact, the ink sheet 2 can be made hard to generate wrinkles.

Title: Rotary tool
Inventor: YAMAMOTO SHINJI
IPC: B23B45/00
Filed: 1993-03-26
Abstract: PURPOSE:To facilitate operations in a small place by providing an output portion to which a tool is attached, and forming a housing into a tapered conical shape from its motor storage portion to the output portion. CONSTITUTION:A housing 1 is largest in width at its motor storage portion 10, and a torque adjusting handle 2, a rotating ring 3 and a chuck handle 40 at a chuck 4 serving as an output portion are disposed in sequence on the outer surface of the end of the housing. The above members are all tapered to form a tapered conical shape from the motor storage portion 10 to the chuck 4 serving as the output portion. Therefore, the end of the tool attached to the chuck 4 serving as the output portion can be visually recognized from behind even during operations in a small space. The direction of projection of an auxiliary grip 30 can be determined so that operations are facilitated and that visual recognition of the end of the tool is not hindered.

Title: Opening and closing mechanism for cover of disk player
Inventor: FUJIWARA SHUNJI
IPC: G11B33/02
Filed: 1990-03-16
Abstract: PURPOSE:To prevent the jump, etc., of a disk accompanying the opening operation of a disk cover while the disk is driven to rotate by forming a disk cover opening spring into a shape to retard temporarily cover opening speed when the cover is transferred to an opened state. CONSTITUTION:When the lock lever of the disk cover 1 is operated in order to take out the disk 7, the cover 1 is moved to an opening direction by the cover opening spring 13. At that time, the bend part 13e of the spring 13 is in contact with the upper end part 2a' of the hole 2a of a chassis 2. The bend part 13e applies resistance to the speed of an end part 13b to move in D- direction so as to retard it. When the cover 1 is moved further to the opening direction, since the end part 13b is moved to D-direction, and the end part 13e is moved more outside than the upper end part 2a' of the hole 2a, the opening speed of the cover 1 is quickened. Thus, since the rotation of the disk 7 is stopped or is decelerated enough before the cover 1 is opened completely, the disk 7 is prevented from jumping because of its own excessive force.

Title: Surface treatment of aluminum
Inventor: ENOMOTO YOSHITAKA
IPC: C23C18/32
Filed: 1990-03-16
Abstract: PURPOSE:To partially deposit an electroless plating without damaging a plating resist and to obtain a dense pattern in a minute range at the time of applying an electroless Ni plating on the surface of an Al thin film by conducting neutral greasing when a substrate is cleaned. CONSTITUTION:A novolac resin is usually used for the positive photoresist material, and hence any problem related to the adhesion, material strength, etc., is not caused in the region ranging from acidic to neutral. However, the resin is easily dissolved in an alkaline soln., and this property is conventionally used for development and to remove the photoresist. Accordingly, a sulfate is added to an alkaline degreasing agent in the degreasing stage in this invention to adjust the pH to neutral, activation is further applied by palladium chloride, and electroless Ni plating is carried out. As a result, even a positive photoresist poor in alkali resistance can be used.

IPC: G03B27/02
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To correct the unbalance of density and color caused by a difference in a production lot and a change in development processing environment. SOLUTION: Photometry for the total average density of each frame of a negative film 18 is executed in each color of R, G and B by a photometry sensor 15. A balance data operation part 16 obtains the average value of three colors, photometric values are classified for underexposure, normal exposure, overexposure and ultra overexposure negatives and density data is accumulated in each three-color. The average value is obtained for each three-color of R, G and B and recorded on the magnetic recording layer of the negative film 18 as balance data. This balance data is read by a printer processor 12 and correction data is computed by a balance correction data operation part. Photometric data obtained by an exposure control scanner is corrected with balance correction data. Then, a printing exposure value is obtained with the corrected photometric data, to execute printing exposure.
